Psalms 139:23

²Examine me, LORD, and prove me. Try my heart and my mind.

⁶(let me be weighed in an even balance, that God may know my integrity);

⁷that the proof of your faith, which is more precious than gold that perishes, even though it is tested by fire, may be found to result in praise, glory, and honor at the revelation of Jesus Christ—

³The refining pot is for silver, and the furnace for gold, but the LORD tests the hearts.

²You shall remember all the way which the LORD your God has led you these forty years in the wilderness, that he might humble you, to test you, to know what was in your heart, whether you would keep his commandments or not.

¹LORD, you have searched me, and you know me.

⁹I will bring the third part into the fire, and will refine them as silver is refined, and will test them like gold is tested. They will call on my name, and I will hear them. I will say, ‘It is my people;’ and they will say, ‘The LORD is my God.’”

²⁰But, LORD of Armies, who judges righteously, who tests the heart and the mind, I will see your vengeance on them; for to you I have revealed my cause.

²“But who can endure the day of his coming? And who will stand when he appears? For he is like a refiner’s fire, and like launderers’ soap; ³and he will sit as a refiner and purifier of silver, and he will purify the sons of Levi, and refine them as gold and silver; and they shall offer to the LORD offerings in righteousness.

¹⁶who fed you in the wilderness with manna, which your fathers didn’t know, that he might humble you, and that he might prove you, to do you good at your latter end;
